Maize (Zea mays), is a plant of economic and nutritional interest, which is often confronted with unfavorable environmental conditions, including water stress. This phenomenon forces the plants to considerably reduce their production by disturbing their metabolism. Seeds of maize of the variety EV8728 were subjected to different doses of gamma radiation (100, 200 and 300 grays) in order to induce mutations in plants that could lead to resistance to water stress. Thus, plants from gamma irradiated seeds were used to evaluate the impact of water stress on leaf physiological parameters (leaf area, density and pore area of stomata and assimilatory pigments). Water stress had a depressive effect on all leaf parameters in maize plants. The degree of sensitivity or tolerance of the plants depends on the dose of irradiation and the intensity of stress applied. The increase in the level of water stress reduces the leaf surface and that of the stomata pores. This in turn increases the density of stomata. In addition, chlorophyll a was more sensitive to the effect of water stress than chlorophyll b.

“…According to Dineva [17] and Brakke et al [31], dorsiventral leaf properties in many leaves is an important characteristic in photosynthesis and gas exchange, and can be affected by air pollution. Indeed, gaseous pollutants mostly enter through the stomata [32], which for F. benjamina are located on the abaxial side [33]. Therefore, it seems that spongy parenchyma is more sensitive to gas exchange than palisade parenchyma, and consequently it is more susceptible to damage from gaseous pollutants [17].…”

The air in African cities is increasingly polluted mainly due to human activities. A bioindication technical of urban air quality based on active remote sensing might be an alternative to existing physico-chemical methods. Reflectance measurements in the visible spectrum have been carried out at the adaxial and abaxial sides of Ficus benjamina L. leaves in the city of Abidjan, Côte d'Ivoire, with a precision digital camera. Leaves were collected in industrial zones and in parks. The impact of air pollution on leaf physiological as well as structural characteristics in these two contrasts urban environments was determined by Dorsiventral Leaf Reflectance Correlation (DRLC) and dorsiventral leaf reflectance asymmetry quantitatively defined with Normalized Dorsiventral Asymmetry Index (NDAI). Species leaf susceptibility to air pollution from season to season was determined by NDAI seasonal variation. Leaf reflectance measurements allowed the estimation of environmental stress level among industrial areas and parks. NDAI and DLRC were significantly higher in industrial zones compared to parks. NDAI values were found significantly higher for major rainy season compared to major dry season, indicating probably that F. benjamina leaf structure changes were increased from one season to another. Thereby, assessment of urban air quality can be done using leaves reflectance in the visible spectrum.

“…Par ailleurs, les caractéristiques des stomates peuvent être utilisées pour l'évaluation précoce de la résistance à la sécheresse ou pour déterminer la vigueur de la plante. En outre, les stomates peuvent être aussi utilisés comme des indicateurs de la pollution locale de l'air (Koffi et al, 2014). L'objectif principal de ce travail est de déterminer les paramètres caractéristiques des stomates chez le palmier à huile normal diploïde afin d'appliquer dans le futur les méthodes de la Biotechnologie.…”
